\1. bootm地址和load address一样 此种情况下,bootm不会对uImage header后的zImage进行memory move的动作,而会直接go到entry point开始执行。因此此时的entry point必须设置为load address + 0x40。如果kernel boot过程没有到uncompressing the kernel,就可能是这里设置不对。 boom address == load address == e...

ep:entry point的缩写,就是程序的入口(类似于mian),一个镜像文件的起始执行部分不是在镜像的开头(镜像开头有n个字节的头信息),真正的镜像文件执行时第一句代码在镜像的中部某个字节处, 相当于头是有一定的偏移量的。这个偏移量记录在头信息中。 (5) ...
